On the silent shutter "need", not only does the shutter on IBIS cameras cause havoc with moving the sensor (and does the M5 not have IBIS), it also creates noisier images and less DR due to an increase in read noise.

 

Sony drops RAW from 14 to 12 bits when using silent shutter mode (or 13 bits to 12 bits).

 

And then there is the rolling shutter issue. It seems the wish for silent shutter is more a specs list reading thing?

 

First of all this is just temporarily valid. A few years back a full electronic shutter didn't exist in photo cameras.

Most of the issues are gone with an electronic first curtain already.

Besides you tend to develop to JPEG thus 8 bits.

Rolling shutter is completely irrelevant for everything but action photography.
